What Counts as Overtime? The FLSA Basics in Plain English

Overtime rules sound complicated because they mix federal law, state law, and job classification. This is a conservative overview of the federal baseline so you know the right questions to ask. It is not legal advice, and it does not cover every state.

The federal baseline: over 40 hours a week

The federal rule comes from the Fair Labor Standards Act, usually called the FLSA. Its core requirement is simple: covered, non-exempt employees must be paid at least time and a half — 1.5 times their regular rate — for hours worked beyond 40 in a single workweek.

Two words in that sentence carry a lot of weight. "Workweek" means a fixed, repeating 7-day period your employer sets; it does not have to match a calendar week, but it has to be consistent. "Beyond 40" means the federal standard is weekly, not daily. Under federal law alone, working a 12-hour day does not trigger overtime unless your weekly total passes 40 hours.

Exempt vs non-exempt: who actually gets overtime

Overtime protection depends on whether you are "non-exempt" (covered by the overtime rule) or "exempt" (not entitled to it). This is where most confusion lives, because being on a salary does not automatically make you exempt.

In general terms, exemption typically requires all of the following to be true, and the details are set by regulation:

• Salary basis: you are paid a predictable salary rather than by the hour.
• Salary level: that salary meets or exceeds a minimum threshold set by the Department of Labor.
• Job duties: your primary duties fit an exempt category, such as certain executive, administrative, or professional roles.

If any piece is missing — for example, a salaried worker whose duties are not exempt, or whose salary is below the threshold — the employee is usually non-exempt and owed overtime. Because the duties test is fact-specific, job titles alone do not decide it.

What counts as "hours worked"

Overtime is based on hours actually worked, and "worked" can be broader than scheduled shift time. As a general matter, time an employer requires or permits you to work counts. That can include certain short breaks, some travel that is part of the job, and required tasks before or after a shift. It generally does not include paid time off such as holidays or vacation, because those hours are not worked, even though they appear on your paycheck.

This distinction matters when you are near the 40-hour line. A week with 38 worked hours plus a paid holiday is 38 hours worked for overtime purposes, not 46 — so it would not trigger federal overtime, even though you were paid for 46 hours.

How the pay is calculated once overtime applies

Once hours pass the threshold, the math is the straightforward part. Overtime hours are paid at 1.5 times the regular rate of pay. The "regular rate" is not always just the base wage — it can include certain non-discretionary bonuses and shift differentials averaged into an effective hourly rate. For a typical hourly worker with no extras, it is simply the hourly wage.

To see the numbers for your own situation, the time and a half calculator handles the 1.5× case, and the overtime calculator combines regular, overtime, and double-time hours into one weekly breakdown. If you are salaried and need an hourly figure first, the salary to hourly converter makes that conversion.

Questions worth asking

If you are trying to figure out whether a specific week qualifies, these questions usually get you to an answer:

• What is my employer's defined workweek, and did my worked hours pass 40 within it?
• Am I classified as exempt or non-exempt, and does that classification match my actual duties?
• Does my state add daily overtime or double-time rules on top of the federal standard?
• Is my "regular rate" just my wage, or does it include bonuses or differentials that should be averaged in?

When to get a definitive answer

This guide is meant to orient you, not to settle a dispute. Classification and regular-rate questions have real financial stakes and depend on facts specific to your job. If you think you have been misclassified or underpaid, your state labor department and the U.S. Department of Labor publish official guidance, and an employment attorney can review your situation directly.

This article is general information, not legal, tax, or payroll advice, and it does not cover state-specific rules. The federal FLSA baseline is time and a half for hours over 40 in a workweek; some states require more. Rules and thresholds change over time. Confirm your situation with your employer, your state labor department, or a licensed professional.
